These
fierce predators resemble some bastard version of scorpion and
spider. The body is wide like that of a spider, but it has has six
jointed legs and two cruelly barbed claws. Its color is dull gray
with streaks of crimson or bright blue.

Much
like a scorpion, the grougge has a tail. This segmented member ends
not with a stinger but with a glowing blue point which the
creature uses to administer an electric shock. It can deliver this
attack once every two melee rounds, doing 3-8 points of damage to any
one target within 2”. No saving throw is possible, but the grougge
needs to make a “to hit” roll. Against victims in metal armor,
the attack is at +4.
